[library concept] Harmony (JavaScript and Server side validation simplified)

[eluser]Michael Wales[/eluser]
I love this idea. I always develop my applications with nothing bu normal HTTP requests in mind, that way I know it works for everyone. Then I go back and add all of the client-side validation, AJAX requests, etc.

Would be nice to have a few helpers/libraries out there that would speed this process up and keep us from having to duplicate our efforts.
